Embodiment -1

[0156] The present invention will be further illustrated by the following examples, but it is not meant to limit the present invention.

[0157] (1) Preparation of photographic photosensitive material

[0158] Preparation of Sample 101

[0159] On an uncoated cellulose triacetate film support having a thickness of 127 µm, various coatings were formed according to the following formulations, and the resultant multi-coated color photographic photosensitive material was Sample 101. Each number in the formula below represents the amount added per square meter.

[0160] First coat: anti-halation coating

[0161] Black colloidal silver halide 0.25g

[0162] Gelatin 2.40g

[0163] UV absorber U-1 0.10g

[0164] UV absorber U-3 0.10g

[0165] UV absorber U-4 0.10g

[0166] High boiling point organic solvent oil-1 0.050g

[0167] High boiling point organic solvent oil-2 0.050g

[0168] High boiling point organic solvent oil-5 0.010g

[0169] Dyes-4 1.0 mg

[0170] Dyes-8 2.5...

example 1

[0454] Compounds I-9, I-17, I-18, I-19 and I-21 of the present invention mentioned in Example 1 were each prepared as a 0.1% solution. Add 5 ml of these solutions per liter of black and white developer replenisher. Each of these samples was tested in the same manner as in Example 1. The results confirmed that the obtained effect was exactly the same.

[0455] Therefore, it can be seen that the anti-foaming agent according to the present invention can be added to the replenishing liquid as in the composition mentioned in Example 1. From the viewpoint of operability and softness, it can also be combined with a liquid as shown in the results of Example 2. It is used in the form of a substance [mixed processing agent].

example 3

[0457] 5 ml of the 0.1% solution of the compound of the invention prepared in Example 2 was added per liter of the color developing solution in Example 1. As a result, the color developing solution is substantially free of foaming, eliminating the occurrence of streaks in the processing bath. In other words, it shows that the anti-foaming agent of the present invention is also effective for color developing solutions.

Abstract

The defoaming agent composition for a silver halide photographic processing solution contains at least one polyoxyethylene / polyoxypropylene copolymer as surfactant.

Description

technical field [0001] This invention relates to anti-foaming agent compositions for use in silver halide photosensitive (black and white and color) processing solutions and in particular to anti-foaming agents which can be preferentially used in a first black and white developing solution for silver halide Reverse color photography and / or its supplements. More preferably, the present invention relates to anti-foaming agent compositions for reducing developer streaking caused by bubbling of the developer and methods of processing silver halide photographic materials using the compositions. Background technique [0002] After exposure, the silver halide color reversal photographic material usually undergoes first black and white development, ashing, reverse development and desilvering to form a reverse color image on it. Silver halide photographic materials contain various surfactants so that when these surfactants are eluted with the developer during the development process...
